A clamped, circular plate under uniform pressure simulating a U-tube heat exchanger tubesheet is studied to ascertain the effect of tube rotational restraint on the tubesheet design. This effect is not normally considered in tubesheet design; however, it is shown here that for low-pressure units, the inclusion of tube rotational stiffness can lead to a measurable strengthening effect.
